A confirmatory factor analysis was used to determine the respective viability of factor structure models for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization data. The traditional verbal-performance split was compared to an alternative model proposed by Gutkin, Reynolds and Galvin. The confirmatory analysis indicated that the Gutkin model provides a superior fit to the data at all age levels and for the total samples. In addition, the results from Gutkin model analyses at each age level were iterative, yielding a refinement in the respective age specific fits of the model. Clinicians should take this finding into account when scoring WAIS-R results. (Author)
